I can't believe I've been mixing water for 2+ years without this. Not that my salinity was way out of whack but this is just so easy to use. Now if only they made a Nitrate tester......

Love it but don't trust it yetBy Kevinon 9/14/2016

I got this because I have a hard time seeing where exactly the blue line is on the standard units. So I love the digital reading but I haven't had long enough use to speak to the reliability over time.

Must be consistent, then there are no issues!By Robon 7/10/2016

Rob would recommend this product to a friend

Even though this meter is digital, you must follow a consistent process to test your water. For instance, if you have a difference in temp between your calibration fluid and the test water, AND YOU DONT WAIT FOR THE METER TO ADJUST THE TEMP, you will have inaccurate readings. Also, the calibration solution is not accurate. I believe mine to be 1.024 - I use my RO water to calibrate and then test tank water and it has been very consistent. I like this because it is much easier for me to read and any variance I feel is far less with this meter than me reading a fine line refractometer.

Tolerance of .002By Sethon 6/8/2016

Seth wouldn't recommend this product to a friend

If your happy mixing you water to 1.025 and finding out that it can be plus or minus 0.002 then this is the unit for you.

If you actually care to know exactly what your water is at buy the standard refractometer and calibration solution and check your calibration often.

Don't even think about contacting Milwaukee for service unless your unit is out of 0.002 variance. They will give you some long excuse how not every unit is make perfect and it's within specs sorry. I will be selling this piece of junk.

It was good at first but...By Tomon 5/11/2016

Tom wouldn't recommend this product to a friend

I had this product for almost 5 months now and for the few months it worked well. Then after that I've been getting inaccurate readings from the unit. It kept saying that my salinity in my tank is 1.024 when its really at 1.026. I tried calibrating it with steamed distilled water and the calibration solution that came with the kit but it was still giving inaccurate reading. The calibration solution is at 1.025 and it reads 1.024.

works great and calibration is simpleBy rblarmeron 4/7/2016

rblarmer would recommend this product to a friend

just go this three weeks ago so longevity not known but definitely easy to use and calibration is simple. Only negative thus far is power on/off button ok but a little quirky thought I had a bad battery and put new battery in and still would not power up so pushed a little firmer and came on, not the way a great quality switch works.

Nice and easyBy MOon 3/28/2016

This is great calibrates easily and fast accurate readings. As I get older my vision is fading and trying to read a sight Refractometer is getting hard, this has nice bright and big numbers for me.

Awesome addition!By jsbullon 1/2/2016

jsbull would recommend this product to a friend

I love this thing. It's super easy and super fast. I calibrated it the first time I used it and haven't had to recalibrate it since (2 months). I can take it anywhere and did I mention it's super easy and super fast?!?

I do wish the case had more room to store the test solution and pipet.

this is by far a must have for reefers its extremely accurate and instant so can't go wrong with that

If been using a refractometer for a few years now, and I don't know why I waited so long to get this. So much easier to zero than the regular refractometer. If you are dedicated to Reefing this buy is a no brainier. Calibration solution are point on and I have no issues. All I can say is this should be one of your first buys if you plan on getting into the saltwater hobby.

The new Milwaukee MA887 Seawater Digital Refractometer encompasses 3 different types of user selected scales for the measurement of seawater providing for a much more precise evaluation. Each scale is temperature compensated.

PPT - The old standard of Parts Per Thousand of saturated salt. This is the oldest of the 3 seawater measurements scales

S.G. - The current standard of Specific Gravity hydrometers and refractometers.

The Milwaukee Instruments MA887 digital refractometer is easy to calibrate and easy to read and provides highest accuracy possible for the measurement of seawater 3 specific scales. This is the type of accuracy demanded by today’s professionals and Milwaukee Instruments delivers.
